Deana

Deana is considered to be a variant of Diana, but is more likely a feminine version of Dean. It could also be a variant spelling of Deanna, but it's recommended that if you want the name to be pronounced like Deanna (dee-anna), then you should spell it Deanna. Most people are going to pronounce Deana as if it were Dean with an a on the end, and you wouldn't want your daughter to spend half her life correcting the pronunciation efforts of strangers. Deana was used some between the 1940's and the 1990's, but was never really popular, and has now disappeared from the U.S. top 1000. There is some renewed interest in the name however, so it might be worth keeping an eye on.
